hi can you show working out as i want to compare it to my answers and see if i got it correct or not

Unfortunately, when student B handed the baton over to student C, student C didn't hold it and dropped it at his starting position (:3). Student C then spent 4.00 second to get the baton back and continue the race. Student C passes the baton to student D at @ who then finishes the relay at CD. When student B arrives at @ and hands over the baton, the sports teacher starts running anticlockwise from (-57) around the track towards (D. Assume all the runners run with constant speed and baton hand overtime is zero. A. What is the net length of displacement from {D to {3}? (4 marks) E. Find the speed of each student (It is better to keep 3 decimals). [5 marks) C. What is the average speed of the relay team when they complete the 400 m track of this event? (4 marks) D. What was the average velocity of the first three members (A, B, and C] of the relay team at position ('1)? [4 marks) E. When and where does the teacher E catch up with the relay team member [i.e., member C or D}? [3 marks] Problem 1 {25 Marks] A school 4 x 100m relay team includes 4 members (A, B, C and D]. A sports teacher {E}, who runs much faster than the students, has his starting position at TDD m from (:3), see diagram below with track positions CD, '2), G), ('1), and (3. Every member in the relay team runs 100 m [times shown in the Table below) before handing over the baton to the next team member. The running curved sections are 160m long semicircles. Time for 100 m [sec] 13.8 14.0 14.6 13.6 11.6 100 m 100 m Problem 2 [25 Marks] A cannon, placed at the bottom side of a hill, fires a cannon ball toward the hill. The slope of the hill is uniformly upward at an angle of 20. The initial velocity of the ball is 100 mfs, at an angle of 55 from the horizontal, see schematic diagram below. Ignore air resistance. A. What are the horizontal and vertical components of the initial velocity of the cannon ball? (5 marks] B. What is the maximum height of the cannon ball during projectile motion. [6 marks) (2. At what distance up the slope (point P} and when does the cannon ball strike the hill? [10 marks] D. lfair resistance is considered, what is the changes in distance of P up the slope and total fly time of the cannon ball (with respect to Part C above): {i1 Distance P: less, greater or no change; (iil Total ball fly time: shorter, longer or no change. [4 marks] Problem 3 {25 Marks) A simple mechanical system is shown in the figure below. All pulleys are frictionless, and all cables are rigid. A. Draw free body diagram for the three objects (MA, MB, and MC). [3 marks] B. When the system is in equilibrium and the weight of M; is 200 N, find the masses of MA, M3, Mc, and the tensions T1, T2 and T3. [10 marks) C. With the same angles of the cables as shown in the diagram. If we change the mass of Mp, to 30.0 kg, what are the new tensions of the three cables at the initial state and the initial acceleration of Mn? {3 marks] D. Why was it specified "initial acceleration\" in Part C? Does the acceleration change with time or not? Provide your explanation [4 marks}
